get the Track Editor software, when you open it you can set how many and what type of track packs you have, and it also includes many different tracks preloaded.Try doubling the length of the tracks etcBhttp://realfxandhotwheels.blogspot.com/

Thanks for your answers. Frindly spoken I dont want to spend much Money on Expansion packs because a lot of the track parts tore after building the 3rd or 4th track. They are not very durable. For that Quality its to expensive.
